Slayer has always been one of the most rewarding skills in both Old School RuneScape (OSRS) and RuneScape 3 (RS3). In 2025, it remains a staple for players looking to earn solid GP and combat XP while progressing naturally. Whether you’re grinding for 99 or just want passive profit with every kill, certain Slayer tasks stand out above the rest.

This guide highlights the best mid-to-high-level Slayer tasks in OSRS and RS3 for gold farming, XP efficiency, and consistent loot — along with tips, gear recommendations, and average GP/hour estimates.

1. Why Slayer is Ideal for Passive Profit

Unlike most gold-making methods that require intense focus or flipping skills, Slayer offers a more balanced approach:

  • Consistent XP and GP: Earn combat XP and Slayer XP while looting valuable drops
  • Unlocks high-tier content: Many bosses and profitable mobs are Slayer-task only
  • Low-risk profit: Most tasks are done solo or in safe zones
  • Great for Ironmen and mains alike

Slayer is also highly scalable. You can AFK some tasks or speed-run high-tier monsters depending on your setup and goals.

2. Best Slayer Tasks for OSRS (2025)

Here are the top money-making and XP-efficient tasks for mid-to-high-level OSRS players:

  • Nechryaels – High profit from Rune items, alchables, and hard clue scrolls. Up to 1.5M GP/hour.
  • Dust Devils – In a cannon-safe multi-area, these drop alchables and valuable seeds. 1M–1.3M GP/hour.
  • Greater Demons (in Catacombs) – Passive totem pieces, ancient shards, and a chance at hard clue scrolls. Ideal for semi-AFK slaying.
  • Abyssal Demons – With a whip drop still valued well, they remain great for profit + XP. Up to 1.2M GP/hour.
  • Kraken (Boss Task) – Highly profitable if unlocked. Up to 1.5M–2M GP/hour depending on luck.

Recommended Gear for OSRS Slayer:

  • Melee Setup: Slayer helm (imbued), Abyssal whip or Arclight, Dragon defender, proselyte or Bandos
  • Ranged Setup: Blowpipe, Karil’s or Armadyl, Ava’s assembler
  • Inventory Tips: Bring a bonecrusher, herb sack, and alch runes to maximize passive gold gain

3. Best Slayer Tasks for RS3 (2025)

RS3 Slayer offers a more advanced and profitable path, especially with the addition of Slayer contracts and elite mobs. Here are top picks:

  • Abyssal Lords & Beasts (Slayer Tower Dungeon) – High-level task that drops Hydrix and T92 components. 3M–6M GP/hour.
  • Ripper Demons – Notorious for their drop table, these can net serious GP with Powerburst + Bladed Dive setups.
  • Living Wyverns – Great for both bones and rare loot. With the right gear, can hit 2.5M+ GP/hour.
  • Creatures of the Lost Grove – Great task for Spiritbloom seeds and rare bow drops.
  • Automaton Slayer Tasks – Accessible from mid-levels, can yield decent cash with proper mechanics.

Recommended Gear for RS3 Slayer:

  • Melee: T85+ weapons (Drygores or better), revo++ or manual with ability rotation
  • Magic: Noxious staff or Staff of Sliske for AoE tasks
  • Useful Auras: Vampyrism, Mahjarrat, and Penance to reduce supply costs

4. Tips for Slayer Efficiency

To get the most out of every task, follow these tips:

  • Always use Slayer Helm (imbued for OSRS) — it boosts both accuracy and damage
  • Block low-profit tasks: Use your task slots wisely (e.g., Turoths, Kurasks, etc.)
  • Use a Cannon (OSRS) or Aggression potions (RS3) to speed up kills dramatically
  • Stack clues, bones, and alchables: Use looting bag, bonecrusher, and herb sack
  • Bank in between tasks: Don’t waste inventory space — efficiency adds up
